An FTP of 200 watts puts you in the sport — competitive at local club and gran fondo level range. FTP (Functional Threshold Power) represents the highest power you can sustain for approximately one hour, estimated here at 95% of your 20-minute best effort.
Your power zones above define specific intensity targets for structured training. Most of your riding should be in Zone 2 (endurance), with targeted intervals in Zones 4-5 to build threshold and VO2max fitness. Zone 6 and 7 efforts are reserved for short, high-intensity bursts.
Use these zones to structure your training. A typical week might include 3-4 endurance rides in Zone 2, one or two threshold sessions in Zone 4, and one VO2max workout in Zone 5. Aim for a weekly TSS between 300 and 500 to build fitness sustainably.
